With a 3\/16 inch head diameter and an 82-degree included angle, this tool is sized for standard flat-head fastener applications where precise seat geometry is required. The 4-flute configuration promotes smooth cutting action and reduces chatter, resulting in a consistent finish. The straight cylindrical shank provides secure tool holding in standard drill chucks and collet systems. This countersink is a common choice for machinists, toolmakers, and production floor technicians working on precision fastener prep operations.\u003c\/p\u003e\n\u003cp\u003eThis countersink suits applications in light to medium machining environments where small-diameter, tight-tolerance countersinking is needed. The 82-degree included angle matches the seating geometry of most standard flat-head machine screws and aerospace-style fasteners. The 3\/16 inch shank diameter fits commonly available drill chucks and collet holders without requiring adapters. Typical use cases include deburring drilled holes, chamfering edges, and seating flat-head fasteners flush with a workpiece surface in both manual and CNC-assisted setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16 inch head diameter for small-fastener and tight-clearance countersinking work\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches standard flat-head fastener seat geometry\u003c\/li\u003e\n  \u003cli\u003e4-flute design reduces chatter and produces a consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank for direct chuck or collet mounting without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style countersink for use with standard flat-head fasteners requiring an 82-degree seat angle; fits drill chucks and collet systems accepting a 3\/16 inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by a machinist or toolroom technician in a drill press, milling machine, or CNC spindle using a compatible chuck or collet. Secure the shank fully in the tool holder before operation and verify spindle runout is within acceptable limits to avoid premature wear. Carbide tooling is brittle — avoid lateral loading or impact during setup. Use appropriate cutting fluid for the workpiece material and operate at manufacturer-recommended speeds for carbide in the target material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 334-302060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728943743282,"sku":"334-302060","price":53.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86c155a711e90400676b66f7fc7dec08.jpg?v=1788697904","url":"https:\/\/voomisupply.com\/products\/hertel-334-302060-countersink-3-16-in-82-deg-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
